Final answer:
Without the total square footage covered by the wallpaper, it's impossible to determine the cost per square foot from the options provided.
Step-by-step explanation:
The question does not provide enough information to determine the cost of wallpaper per square foot directly. However, the provided options imply a need to analyze the structure of the figures. Considering the question's structure, if we assume that the square footage of wallpaper relates directly to these monetary values (which is often the case when determining the cost per unit area), we would look for a figure among the options that makes sense when divided into the total cost of the wallpaper.
To find the cost per square foot, you take the total cost of the wallpaper and divide it by the total number of square feet covered by that wallpaper. Without the total square footage provided, we cannot calculate the correct answer based on the provided information. Therefore, it is not possible to accurately select from the options (a), (b), (c), or (d) without additional data.
The additional reference costs provided from past shopping experiences or other purchases do not pertain directly to the question at hand, as they represent different totals unrelated to the wallpaper scenario. These cannot be used to determine the cost per square foot of the wallpaper without knowing the relationship between the total costs and the square footage they represent.
